UNITED STATES PATENT FIFICEQ JOHN J. HOPP ES, OF SPRINGFIELD, OHIO.

FEED-WATER HEATER AND PURIFIER.

SPECIFICATION forming part of Letters Patent No. 369,7l4=, dated September 13, 1887. Application filed January 12, 1887. Serial No. 224.165. (No model.)

To aZZ whom, it may concern:

Beit known that I, JOHN J. HOPPES, a citizen of the United States, residing at Springfield, in the countyfigdi Olark and State of Ohio, haveinvented certain new and useful Improvements in Feed-Water Heaters and Purifiers, of which the following is a specification.

My invention relates to feed-water heaters and lime-extractors for steam-boilers; and it particularly relates to that class of heater in which the water is adapted to flow along the the plates therein.

under side of a plate or pan and deposit its incrustatin g substances thereon.

It also relates in its nature to the class of heaters shown and described in my patent, No. 318,112, May 19, 1885, and in my applications Nos. 221,796 and 221,797, filed in the United States Patent Office.

My invention consists, primarily, in a corrugated plate or plates arranged vertically in an outer casing in such amanner thata series of inclined surfaces are formed, along the under side of which the water fed to the said heater is adapted to pass.

My invention further consists in a series of pans or troughs formed on the said corrugated plates to receive and retain a portion of the water therein.

My invention further consists in a feeding arrangement of novel construction in connection with the pans or troughs, whereby the water is distributed to the respective plates according to the capacity thereof.

My invention further consists in various constructions and combinations of parts,hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l-is a transverse sectional elevation view of my heater, showing the general arrangement of Fig. 2 is a perspective view of one of the plates in detail, showing the manner of supporting and adjusting the same. Fig. 3 is an end elevationview of one of the plates enlarged. Fig. 4 is a partial sectional elevation showinga modification of the feeding device.

In the said drawings,A represents the outer shell or casing, which is preferably made of a plain cylindrical form, and which is adapted to be connected to a steam-boiler from which steam is supplied, or to the exhaust-pipe of the engine, in any wellknown manner.

B B are the plates, any number of whichmay be used, as desired. The plates B are each preferably constructed from a singlepiece of sheet metal, formed with a series of corrugations, a a, and provided at the top with an overflow pan or trough, b. The plates B are secured vertically in the outer casing, A, so that a series of inclined surfaces, 0, are formed by thesides of the corrugations a. The overflow trough or pan 1) is so constructed that the water discharged therein will flow over the respective sides thereof and in a uniform sheet along both sides of the corrugated plate B, passing alternately over the upper and under sides of theinclined surfaces 0. By this construction the water will be brought into direct contact with the steam in the outer casing, and the incrustating substances contained in the water will be deposited on the inclined surfaces 0 of the corrugated plate.

I preferably provide each of the plates Bat intervals with auxiliary plates or pans (l, which I secure to the under side of the corrugations a in such a manner as to form with the next succeeding corrugation a pan, (2. The under surface of the inclined sides 0 is thus extended, and the water passing over the respective sides of the plate B is caught at intervals and retained at rest to permit any free solids therein contained to settle,after which it again flows along the under surface of the next successive pan or corrugation, and so on until all theimpurities are deposited in the said pans or along the inclined surfaces of said plate.

As before stated, the plates 1) are preferably arranged in a series ina cylindrical casing, A, which is preferably placed ina horizontalposition. By this arrangement the outer plates or pans farthest from the center of the case will be smaller than the inner ones.

The feed-wateris fed to the overflow troughs or pans b by means of pumps or from any convenient source of supply. In order to convey the water to the respective plates in a quantity corresponding to the capacity thereof, I provide at the top of the outer casing,A, a feeding-chamber, G, from which lead small inlet pipes or couduitsfflf and f, of different sizes, corresponding to the capacity of the plate it is adapted to supply. The feed-water is fed to the chamber 0 by the feed-pipe D in the usual manner. The inlet-pipesf,f, and f are preferably provided with means for varying the quantity of water which flows through the same, in order that the supply to the respective plates may be accurately regulated. This may be accomplished by placing in the supply-pipesf, &c., valves h, h and h, as shown in Fig. 4. Instead of having the feeding-chamber 0 formed in a single piece, it may be constructed of pipe of different sizes, as shown in Fig. 4.

The outer casing, A, is provided at either end with removable heads in the ordinary manner, and the plates B are adapted to be readily removed therefrom for cleaning,as desired. The plates I preferably suspend from the top of the heater by hooks Z, which rest on ways or slides Z, secured in the top of the heater. Means are preferably provided for adjusting the plates to a Vertical position, so that the water will flow evenly over the respective sides thereof. This I accomplish by providing at the bottom of each plate projeeting lugs m, and providing on either side thereof adjusting-screws 41, adapted when moved in either direction to move the plate B, and thus furnish the means of adjusting the plates to a vertical position in the outer casing, A.

It is obvious that the auxiliary pans or plates 6 may be placed on each of the corrugations a, if desired; or they may be omitted entirely, depending on the character of the water with which they are adapted to be used. In many cases the overflow trough or pan 1) will alone be found sufficient to collect the free solids contained in the water fed thereto.

It is obvious that various modifications may be employed in the arrangement and construction of the various parts herein described. Instead of placing the outer casing horizontal, it may be placed vertical and the plates extended vertically through the same.

It is obvious that the constructions herein described may be used as a live-steam heater or as an exhaust-heater, the connections being modified to suit the particular case.

Instead of having the plates formed from a single piece, they may be formed of one or more pieces, as shown in Fig. 4, in which case the ends of the respective pieces may be turned up or extended to form the pockets or pans.

It will be seen that the water fed to the heater will pass evenly along both sides of the corrugated plates B, and will pass along the under sides of the inclined surfaces 0, and, coming in direct contact with the steam in the outer casing, will part with its incrustating substances, which will be deposited on the inclined surfaces.

The plates B are preferably formed of sheetsteel, the resilience of which will enable the incrustations to be readily removed therefrom. They may, however, be made of any other material suitable for the purpose.

Having thus described my invention, I claim- 1. The combination, with an outer casing provided with means for introducing steam therein, of a corrugated plate arranged vertically in said casing in such a manner that a series of inclined surfaces are formed, and means for introducing the feed-water to said plate, so that it will flow along the under side of said inclined surfaces in direct contact with the steam, and thus deposit the incrustating substances on said inclined surfaces, substantially as set forth.

2. In a feed-water heater, a corrugated plate arranged vertically in an outer casing, so as to form a series of inclined surfaces, along the under side of which the water is adapted to flow, said plate being formed with an overflow pan or trough at the top, said pan being closed at the bottom and provided with overflow-edges, over which the water is adapted to pass, and thus be distributed equally to the re spective sides of said plate, substantially as set forth.

3. In a feed-water heater, the corrugated plate arranged vertically in an outer casing and auxiliary plates secured to said corrugations to form pockets or pans thereon and cause the water to flow on the under side of said corrugations, substantially as set forth.

4. In afeed-water heater, a series of plates or pans of different capacities and a feedingchamber having inlet pipes or conduits of dif ferent sizes leading from said feeding-chamber to the respective plates, substantially as set forth.

5. In a feed-water heater, a series of plates or pans of different sizes, a feeding-chamber having separate pipes or conduits leading therefrom to the respective plates or pans, and means for independently regulating the quantity of water fed through the respective conduits or pipes to the said plates, substantially as set forth.

6. In a feed-water heater, a corrugated plate arranged substantially vertical in the outer casing, and having an overflow box or pan at the top thereof, and means for adjusting said ,plate to a vertical position, substantially as set forth.

' -7. In a feed-water heater, the outer casing containing a series of corrugated plates arranged vertically therein and provided, respectively, with an overflow trough or box at the top thereof, and a feeding-chamber having independent conduits leading to the respective plates, substantially as set forth.

8. In a feed-water heater, the outer casing containing a series of corrugated plates arranged vertically therein, said plates being provided at the top with an overflow box or pan and provided at intervals on the corrugations with auxiliary plates or pans, and means for feeding the water to the respective plates, so that it will flow along the under sides of IIO the respective corrugations, substantially as set forth.

9. In a feed-water heater, the outer casing containing a series of corrugated plates, each provided at the top with an overflow pan or trough and provided at intervals on the corrugations with auxiliary plates or pans, means for feeding the Water to the respective plates, so that it will flow along the under side of the respective corrugations, and means for adjusting the said plates to a vertical position in the outer casing, substantially as set forth.

10. In a feed-water heater, the cylindrical outer casing containing a series of corrugated plates of different sizes arranged vertically In testimony whereof I have hereunto set my 25 hand this 4th day of January, A. D. 1887.
